How do I know which algaecide is polyquat

[aodino]

If I want to use a (as recommended) polyquat algaecide for pool closing, how do I know if the one I may purchase is a "polyquat" type of algaecide? Will it state that on the container?

And the closing info on this forum says to spread evenly with a leaf skimmer or etc... does this mean such an algaecide is in powder form or is it liquid?

Thanks

Active ingredient -

Poly{oxyethylene(dimethyliminio)Ethylene (dimethyliminio)ethylene dichloride}

60% concentrate in water

If it says -

alkyldimethylbenzylammonium chloride

That is a linear quat algaecide and you do not want that.
